DETAILED DESCRIPTION OF THE INVENTION

The technical solutions of the present disclosure will be clearly and completely described in the following with reference to the accompanying drawings. It is obvious that the embodiments to be described are only a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by persons skilled in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

Referring to FIG. 1, FIG. 1 is a flow chart of a split-screen display method according to an embodiment of the present disclosure. The split-screen display method is applicable to a display apparatus including a curved display screen. The curved display screen can be bent into a plurality of curved display screens by an external force. As shown in FIG. 1, the split-screen display method includes steps S101 to S104.

At S101, position information of a moving path of the curved display screen is recorded when it is detected that an user bends and splits the curved display screen according to a preset fold line, and the preset fold line is a dividing line between the adjacent curved display screens formed by the bending and splitting.

In the embodiments according to the present disclosure, when a plurality of users are viewing picture content on the curved display screen, if the users want to view different picture content simultaneously on the curved display screen, the curved display screen can be bent into at least two curved display screen according to the preset fold line by the external force, and the preset fold line is the dividing line between the adjacent curved display screens formed by the bending and splitting. Specifically, referring to FIG. 2 and FIG. 3, FIG. 2 is a schematic view of a user viewing a curved display screen according to an embodiment of the present disclosure, and FIG. 3 is a schematic view of an effect of users viewing a curved display screen with a split-screen display method according to an embodiment of the present disclosure. As shown in FIG. 2, the curved surface display screen 10 is provided with a preset fold line 101, and the preset fold line 101 may be plural. When a plurality of users (such as a user 21 and a user 22) are viewing programs using the curved display screen 10, if the user 21 and user 22 want to view different programs simultaneously using the curved display screen 10, the curved display screen 10 can be bent and split according to the preset fold line 101, i.e., the preset fold line 101 can split the curved display screen 10 into two curved display screens. As shown in FIG. 3, the curved display screen 10 is bent into a first curved display screen 11 and a second curved display screen 12 according to the preset fold line 101. When the preset fold line is plural, the curved display screen can be split into a plurality of curved display screens. For example, for a second preset fold line 102 and a third preset fold line 103 in FIG. 4, the curved display screen 10 can be split into the first curved display screen 11, the second curved display screen 12, and a third curved display screen 13 according to the second preset fold line 102 and the third preset fold line 103.

When it is detected that an user bends and splits the curved display screen according to the preset fold line, specifically a sensor can be used to perform the detection. For example, a pressure sensor may be set at the preset fold line, and when the pressure value detected by the pressure sensor reaches a certain preset pressure threshold range, it is determined that the user is bending and splitting the curved display screen according to the preset fold line. At this time, position information of a moving path of the curved display screen is recorded. Specifically, the preset fold line includes but not is not limited to a vertical fold line. If the fold line is the vertical fold line, then corresponding column pixel units of the vertical fold line on the curved display screen is obtained, and the column pixel unit can be used as the position information of the vertical fold line on the curved display screen. Further, the position information of the preset fold line on the curved display screen can also be determined by other manners.

At S102, a display interface of the curved display screen is divided into a plurality of sub-interfaces according to the position information, and a splitting line between two adjacent sub-interfaces coincides with the preset fold line.

In the embodiments according to the present disclosure, when the display interface of the curved display screen is divided into a plurality of sub-interfaces according to the position information. Specifically, the display interface of the curved display screen 10 may be divided into a sub-interface of the first curved display screen 11 and a sub-interface of the second curved display screen 12, the two sub-interfaces are independent, and they can be shrunken versions of the display interface of the original curved display screen 10, or be new display interfaces. The most important is that the splitting line between the two sub-interfaces coincides with the preset fold line, and the position of the splitting line is depended on the preset fold line on the curved display screen. Thus, according to the physical splitting of the curved display screen (the hardware is bent into a plurality of display screens), the splitting display of the display interface is correspondingly realized on the software.

At S103, display content selected by the user in the sub-interfaces is obtained.

In the embodiments according to the present disclosure, the display content selected by the user in the sub-interfaces is obtained. Specifically, if the user 21 and user 22 want to view different picture content simultaneously, after the aforementioned steps, the users can select different content of video or text in the sub-interface of the first curved display screen 11 and the sub-interface of the second curved display screen 12. For example, the user 21 selects a video A in the sub-interface of the first curved display screen 11 and the user 22 selects a video B in the sub-interface of the second curved display screen 12, then the display content selected by the users is obtained, i.e., the video A and the video B.

At S104, the display content selected in the sub-interfaces is displayed via the sub-interfaces.

In the embodiments according to the present disclosure, for example, the user 21 selects the video A in the sub-interface of the first curved display screen 11, then the video A is displayed via the sub-interface of the first curved display screen 11. The user 22 selects the video B in the sub-interface of the second curved display screen 12, then the video B is displayed via the sub-interface of the second curved display screen 12. In this way, different users can view different display contents through different screens corresponding to the curved display screen and the display interface. When the display screen corresponding to the preset fold line is bent, it protrudes from the curved display screen, thus the preset fold line can also cover the display content of the sub-interfaces on both sides of the splitting line, such that the users can truly enjoy the effect of two display screens. Unlike the conventional splitting screen technology, it is realized that different users can view different content by using a same display screen, with no interference.

The most important is that the splitting line between the two sub-interfaces coincides with the preset fold line, and the position of the splitting line is depended on the preset fold line on the curved display screen. Thus, according to the physical splitting of the curved display screen (the hardware is bent into a plurality of display screens), the splitting display of the display interface is correspondingly realized on the software.

At S204, display content selected by the user in the sub-interfaces is obtained.

In the embodiments according to the present disclosure, the display content selected by the user in the sub-interfaces is obtained. Specifically, if the user 21 and user 22 want to view different picture content simultaneously, after the aforementioned steps, the users can select different content of video or text in the sub-interface of the first curved display screen 11 and the sub-interface of the second curved display screen 12. For example, the user 21 selects a video A in the sub-interface of the first curved display screen 11 and the user 22 selects a video B in the sub-interface of the second curved display screen 12, then the display content (i.e., the video A and the video B) selected by the users is obtained.

At S205, it is determined whether audio information exists in the display content.

In the embodiments according to the present disclosure, whether the audio information exists in the display content is determined. For example, the display content is video A and video B, then the video A and video B may have audio information. To determine whether the audio information exists, an existing method of audio information detection is employed, and it will not be described in detail herein.
